Clarity
I3 (Included/Industrial Grade)
Shape
Octahedron (Rough/Uncut)
Overall Assessment
This is a low-quality natural rough diamond crystal primarily of interest as a mineral specimen or for raw jewelry applications. Due to the heavy internal inclusions and poor color, it would likely not yield a gem-quality faceted stone.
Cut Quality
Not Applicable (Rough)
Brilliance
Low (Light is absorbed by inclusions rather than reflected)
Fire
None (Cut facets do not exist to disperse light)
Scintillation
Negligible
Proportions
Asymmetric natural crystal habit
Symmetry
Poor (Natural crystalline asymmetry)
Polish
None (Natural matte/striated surface)
Fluorescence
Indeterminate without UV source, likely none
Inclusions
Extensive internal fracturing, multiple dark carbon spots, and green/red surface mineral staining
Blemishes
Surface trigons, percussion marks, and heavy mineral encrustation
Origin
Alluvial deposit likely from Africa or South America
Treatment Detection
No treatments detected; appears to be raw, uncleaned mine-run specimen
Estimated Value
$10 - $50 (Significant lack of transparency and purity)
Certification Estimate
GIA (Rough Diamond Report), would likely be classified as industrial or specimen grade
Investment Potential
Low (Specimen value only, not suitable for high-grade jewelry cutting)

Setting Suggestions
Wire-wrapped jewelry or custom claw setting for a 'raw' organic look
Care & Maintenance
Clean with warm soapy water and a soft brush to remove surface debris
Interesting Facts
Rough diamonds often have 'trigons'—small triangular indentations on the surface that indicate a natural growth process.
